Ziqian Liu received the Ph.D. degree from the Southern Illinois University, Carbondale in 2005. He is currently an Assistant Professor with the Engineering Department, SUNY Maritime College. From 2005 to 2008, he worked in Ingersoll-Rand Co. Ltd, USA. From 1989 to 1999, he was with the Department of Electrical Engineering, Hefei University of Technology, China. His research interests include nonlinear optimal control, intelligent control, motor control systems, DSP or microprocessor-based embedded systems, power electronics and drives, and computational modeling.
Modeling and Simulation of Electric Machinery for Electrical Engineering CoursesAbstract As modern technology advances rapidly, it becomes crucial to train and educate our youngengineering students. From pedagogical point of view, computer simulation provides a hands-ontool for students to gain deep insights on the dynamic performance and interactions of electricmachinery, which often are not easily mastered through studying theory. In industry, modelingand simulation are widely used by engineers as a critical procedure to design an electricmachinery drive in order to save the cost of building a system prototype. When all of thecomponents for a simulation are correctly chosen, the simulation process is able to demonstrateboth steady state and transient performance that would have been obtained if the drive wasactually built. This practice thus saves time, reduces cost of building a prototype, and ensuresthat requirements are met beforehand. In industrial R&D, using Matlab/Simulink in modelingand simulation has played a major role, and become more and more popular. In order to well prepare our engineering students for the challenges presented by advancedtechnologies in the 21st century, we developed a series of Matlab/Simulink programs formodeling and simulation of electric machinery, which is employed for electrical engineeringcourses. In this paper, an intelligent control of induction motor simulation project is presented,which was deployed in a senior design course within our electrical engineering program. Thenew design project includes the following modules: motor module, PWM module, abc-to-dqmodule, dq-to-abc module, three phase current generator module, intelligent velocity controllermodule, and current controller module. Among them, there are several novel modules created bythe course instructor, which replaced those existing ones in Matlab/simulink. For an instance, toclearly visualize the relationship between internal parameters and system performances, all of therelated differential equations were embedded into the models of electrical machines. Thetheoretical derivation, modeling work, and simulation results in the aforementioned project areprovided as follows. On the next page, we give the figure of entire simulation program and one of simulationresults.
